I have the same problem. I just had surgery done so that endoscope thingie iritated the flap in my throat, it turns out i woke up during the procedure and tried to pull it out of my mouth myself, luckily they said they were done, yelled at me to calm down and proceeded to remove it. Im wondering myself how long it will take for the iritation to go away cause i constantly feel like gagging on it, feels like something is stuck in my throat but they did prescribe an antibiotic. So we'll see.
did you ever find out what was causing your arm pain and tingling? I'm having the same symptoms that you described to a TEE. I'm going crazy trying to find out what is wrong. I've had an MRI of my neck to see if it's caused from a bulging disk or something, but it's not. Help!
